Can we take 5mg of melatonin (sold in pharmacies) if we are taking 10mg of Citalopram? Is there any contraindication?

It is generally safe to take melatonin 5mg (sold in pharmacies) with Citalopram 10mg. However, it is important to note that Citalopram can cause drowsiness in some individuals. To avoid potentially intensifying sedative effects, it may be wise to start with a lower dose of melatonin, such as 3mg, and increase to 5mg if needed.
